This is something is something small but....well here it is. It's only happened once to me in over 3 years of using PtokaX, but recently, while in a rush, I clicked "Redirect all users" under the Users / Chat tab, while aiming to tick CMDs. I think it'd be nice, though to have a confirmation popup with something like "Redirect To: <address>" with OK and Cancel. This would make more sense than just dumping everyone into the your set redirect hub in Network. I can imagine many instances where your normal redirect hub might not be where you'd want to send all of your users, and it'd save the step of changing it then having to change it back again afterwards.
I agree that this would be a nice thing... i've redirected all a couple times, when I ment to click the "mass message" button, that I sometimes use when I dont have my dc client open and need to reboot comp, its easier then starting client just for sending a message...
another thing that would be cool, is if there was a option to send a message with the redirect, to tell the users why they are redirected
